Send Transactions on TestNets

Virtual TestNets allow you to send transactions to the virtual network. The process of sending transactions is identical to sending transactions on the real network.

Transactions can be sent through the Dashboard UI or via RPC. This page shows you how to do it using both methods.

Sending via RPC

Use the eth_sendRawTransaction RPC method to send transactions to your TestNet.

The example below shows you how to send a transaction using Viem, Ethers.js and the cURL command. The code snippets are runnable without changes.

    -X POST \
    -H "Content-Type: application/json" \
    -d '{
          "jsonrpc": "2.0",
          "id": 0,
          "method": "eth_sendRawTransaction",
          "params": [

Sending from the Dashboard

Transactions sent from the Dashboard will be recorded in the TestNets state. These transactions do not need to be signed and can be sent to and from any address on the TestNet.

From the Explorer view, click on the Send icon from the top right to access the Send Transaction input form.

Select a contract

In the address field, paste the address of the DAI stablecoin contract:0x6B175474E89094C44Da98b954EedeAC495271d0F.

The receiving contract can be any of the following:

Specify the call data

For contracts that are verified on Tenderly (privately or publicly) or publicly on Etherscan or Blockscout, you can use the Choose function and parameters.

  1. Select the approve function
  2. Paste an address you wish to approve DAI to (0x40BdB4497614bAe1A67061EE20AAdE3c2067AC9e)
  3. Set the wei amount of DAI you want to approve. For example, 10000000000000000000.
For unverified contracts, you need to enter raw input data/calldata in hex form.

Fill in transaction parameters

You can fill in the following options:

  • From: Any account address since transactions on TestNets don’t need to be signed. Use 0xbd8daa414fda8a8a129f7035e7496759c5af8570 or any address you funded with DAI.
  • Gas: Defaults to 800000 or set the desired gas (limit)
  • Gas Price: Defaults to 0 or an arbitrary gas price
  • Value: Defaults to 0 or specify an arbitrary transaction value, that will be deducted from the sender’s (from) balance.

Sender accounts need to have sufficient funds to send transactions. Use the Unlimited Faucet to top up any account with any balance before sending transactions on TestNets.
